Just for fun, I briefly re-wired my brew box (which normally controls a direct-fired {propane via 24V Honeywell valve} RIMS mash unit, aka R2-DBrew) to control my Death Star pumpkin. The Death Star is equipped with a 5 mW green laser wired into a 3V power supply that is switched at 110 line voltage by the BCS. It also controls the light inside Alderaan which illuminates briefly when it explodes. I normally have it running on a loop, but can also fire the laser with my iPhone using a web input.
